Meaning
A specialised cell is a cell that has a special shape or special features to do a certain job in the organism.
About Specialised Cells
- All multicellular organisms have specialised cells.
- Specialised cells make an organism more efficient than if every cell was the same.
- Specialised cells have specific adaptations that make them good at their function.
- Cells can be specialised by having more mitochondria or chloroplasts than usual. They might be specialised with tiny hairs called cilia, or have an elongated shape.
These are some specialised cells in plants that you should know:
